CONCRETE-MOLD.

Specification of Letters Patent.

Application filed January 21, 1911.

Patented Feb. 6, 1912. Serial No. 603,913.

To all whom it may concern Be it known that I, HERREMAN O. MEEK, acitizen of the United States, residing at Garden City, in the county ofFinney and State of Kansas, have invented a new and usefulConcrete-Mold, of which the following is a specification.

This invention relates to concrete molds.

The objects of the invention are to improve, strengthen, and simplifythe construction of the clamping or retaining means for concrete moldboxes or forms, as well as to increase their efficiency in use and todecrease the expense attending their manufac ture.

With the foregoing and other objectsin view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construct-ion hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of invention herein disclosed can be made within the scope ofwhat is claimed without departing from the spirit of the invention.

In the accompanying drawing forming a part of this specification, Figure1 is a perspective view of a mold box or form of the knock-down variety,the boards forming the mold being held in assembled position by means ofthe improved clamping or retaining devices of the present invention;Fig. 2 is a detail view showing in perspective a pair of novel clipsforming part of the present invention, the righthand cl1p being adaptedto engage either the lower edge of the lowermost board of the mold boxor the upper edge 'of the uppermost board thereof, and the left-handclip being adapted simultaneously to engage the upper edge of thelowermost board and the lower edge of the uppermost board, whereby tohold said mold boards in position; Fig. 3 is a detail end elevationshowing a part of one of the end clamping devices shown in Fig. 1, saidend clamping device being partly broken away and the right-hand sidepieces thereof being omitted. Fig. 1 is an end elevation showing theintermediate clamping device of Fig. 1; Fig. 5 is a detail perspectiveview showing one of the adjustable, pivotally movable and detachablelower side pieces, adapted for use in connection with either the endclamping devices or the intermediate clamping device as shown in Fig. 1;Fig. 6 is a side elevation of a partition board adapted for use individing the mold box shown in Fig. 1 into compartments; and Fig. 7 isan edge view of said partition board.

The concrete mold of the present invention preferably includes a moldbox or form of the knockdown variety, as shown in Fig. 1, said formbeing composed preferably of up per side boards 11, lower side boards2-2, end boards 3-3, and, if desired, partition boards such as shown inFigs. 6 and 7 together with any suitable bottom and top boards, notshown.

The means for securing the mold box or form in assembled position duringthe molding operation preferably includes an inter mediate clampingdevice indicated generally by the letter A, and a pair of end clampingdevices indicated generally by B and The intermediate clamping device Aas shown best in Figs. 1 and 4 of the drawing, preferably includes alower cross piece 5, an upper cross piece 6, upper side pieces 7 and 8,and lower side pieces 9, the specific character of which is best shownin Fig. 5. The lower cross piece 5 of the intermediate clamp Apreferably is formed of a fiat bar of metal bent into approximatelyU-shape, the closed end 10 thereof being bent so as to have its plane offlatness lie in a horizontal plane, said bar having its free endstwisted, as indicated at 11, so that said free ends will be disposed invertical planes. The

free ends of the lower cross piece 5 are pro- V v'ided with spacedperforations or openings 12, which serve adjustably to receive bolts 13arranged on opposite sides of the upper side piece 7. By disposing thebolts 13 in different holes 12 the lower cross piece 5 can be adapted todifferent adjustments of the clamp.

The upper cross piece 6 of the clamping device A preferably is formed intwo sections which are pivotally and adjustably connected with eachother by means such as the bolt 14: adapted to be extended through anyregistering pair of openings 15 in the two sections of the cross piece6. The right-hand section of the cross piece 6 in Fig. 4 preferably isprovided with a lateral extension or offset 16 which engages beneath thelower edge of the left-hand section of said cross piece, and therebyserves as a stop to prevent the lower ends of the side pieces 7 and 8from being moved inward at their lower ends any farther than is shown inFig. 4, at the same time permitting said side pieces to be moved freelyoutward. In other words, the offset 16 serves to produce a stop whichwill prevent the joint between the two sections of the upper cross piece6 from being broken upward, but will permit said joint to be broken in adownward direction. By removing the bolt 14 and fitting it intodifferent openings 15, the length of the upper cross piece 6 can beincreased or decreased.

A lower side piece such as 9 in Fig. 5 is adjustably and detachablyconnected to the lower end of each of the upper side pieces 7 and 8.Each of these lower side pieces 9 is provided with a plurality of spacedopenings 20 adapted to be engaged by a bolt 21 which passes through anopening 22 in thelower end of the upper side piece. Each lower sidepiece 9 is provided with an extension or offset 23 which engages theouter edge of the upper side piece so as to prevent the lower side piecefrom swinging outwardly beyond the vertical plane of the upper sidepiece. At its lower end each 'lower side piece 9 is formed with aninward extension 24: which projects below the lower edge of thelowermost side board of the form or mold box.

For the purpose of holding the lower edge of the uppermost form board inposition, as well as to hold the upper edge of the'lowermost form boardand all intermediate boards, a clip such as 25 in Fig. 2, is provided,said clip being preferably, although not essentially, formed of wire orbar metal bent into the shape of the letter U and having one terminalbent upward, as indicated at 26, and the other terminal bent downward asindicated at 27, said clip being fitted around the upper side pieces 78and projecting through the joint between the side boards, one of theterminals 26 holding one board in position, and the other terminal 27holding the other board in position. The closed end of the clippreferably fits into a notch 28 formed in the upper side piece 78.

The upper and lower edges of the form boards are held in position bymeans such as the clip 29 having both of its terminals 8031 extended inthe same direction. If

. it be desired to use a shallow form or mold inost position shown inFigs. 1 and 4, so

as tightly to clamp the form or mold box. Vhen it is desired to open themold box,

the lower cross piece 5 is raised until it engages the notches orcutaway portions 32 formed in the upper side pieces 7 and 8, as shown inFig. l, at which time suliicient play is afforded to the side pieces 7and 8 to permit the form to be removed from the work.

The end clamping devices B and G are practically the same inconstruction as the intermediate clamping device A. The lower sidepieces 9 are the same as those used with the intermediate clampingdevice. The principal feature of difference between the end clampingdevices and the intermediate clamping device is that the upper crosspiece 6 is formed of two single pieces bolted to opposite sides of theupper side piece 7, as indicated at 35, and having in its opposite end aseries of spaced openings 36 by means of which it is adjustablyconnected with the upper side piece 8. Each of the side pieces 7 and 8of the end clamps is extended upward, as indicated at 37, and inward, asshown at 38, and is formed with an internally threaded sleeve portion 39through which extends an adjusting rod 40 which is intended to bescrewed downward onto the upper edge of the boards of the properposition. In other respects, the end clamping devices B and C are thesame as I the intermediate clamping device A.

As the operation of the invention is obvious from the foregoingdescription in connection with the drawing, a specific descriptionthereof is deemed to be unnecessary.

hat is claimed is:

1. A concrete mold comprising a form; side pieces extended along thesides of the form, and having their upper ends pivotally connected,across the top of the form; an arched cross piece having its bendengaged with one of the side pieces, its free ends extending along theother of the side pieces; a connecting element in the free ends of thecross piece, to bind the free ends of the cross piece against the lastmentioned side piece; there being a notch in the outer edge of said sidepiece, into which the connecting element is adapted to move, when thecross piece is slid longitudinally of the side pieces, and in thedirection of its length, the registering of the connecting element inthe notch permitting the side pieces to be swung apart, thereby to freethe sides of the form.

2. A concrete mold comprising a form; side pieces extended along thesides of the form and having their upper ends pivotally connected,across the top of the form; an arched cross piece having its bendengaged with one of the side pieces, its free ends extending along theother of the side pieces; a connecting element in the free ends of thecross piece, adapted to bind the free ends of the cross piece againstthe last mentioned side piece; there being notches in the outer edges ofthe side pieces, into which notches the bend of the cross piece, uponthe one hand, and the connecting element, upon the other hand, may move,when the cross piece is slid longitudinally of the side pieces, and inthe direction of its length.

3. A concrete mold comprising a form; side pieces extending along thesides of the form, and having their upper ends turned to overhang theupper edges of the form; screws threaded into the turned portions of theside pieces, and adapted to bear against the upper edges of the form; anupper cross piece adjustably connecting the side pieces;

and a lower cross piece adjustably connecting the side pieces, below theupper cross piece, the lower cross plece belng of arched construction,and having its bend engaged with one of the side pieces; a connectingelement uniting the free ends of the lower cross piece, to bind the sameagainst the other side piece; there being a notch in' the outer edge ofsaid side piece, which the connecting element is adapted to enter, whenthe lower cross piece is elevated, thereby permitting the side pieces tobe swung apart, to free the sides of the form.

In testimony that I claim the foregoing as my own, I have hereto aifixedmy signa ture in the presence of two witnesses.
